MERWIN, a citizen of the United States, residing at St. Louis, Missouri, have invented a new and 5 usefulGas-Saturating Device, .of which the following is a specification.

This invention relates to gas saturating devices, such as are adapted for use to saturate fuel gas with moisture, and it consists of the novel construction, combination and arrangement of parts herein shown, described and claimed.

The object of this invention is to provide a device for use with explosive gas engines whereby the gas passing to the explosion or combustion chamber will be mixed or saturated with vaporized or sprayed moisture, both of said elements being commingled thoroughly in a mixing chamber which con stitutes a part of the passage leading from the source of supply of each of said substances to the combustion or delivery chamber.or outlet. The mechanism is arranged so that the requisite or desired quantities of the two substancescome together from intersecting passages'so that thenceforward they; move together within a passage or chamber whose outlet is controlled by-suitable valves thereby causing proper convolutions of the vaporous or gaseous elements as required to them thoroughly together. The explo 'sive power or force of the gas is improved by proper saturation thereof, especially saturation as. efficiently eflected by this mechanism.

:There are other objects whichwill appear from the following description, reference being made to 'the accompanying drawing which is a sectional view illustrating a satisfactory embodiment of my invention as 40 adapted for use in connection with engines,

locomotives and like mechanisms. A casting 1 formed with a chamber 2 which leads or opens into the cylinder of the A hollowcasting 3,

enginelnot shown). constituting a passageway, is provided with an elbow. '4 leading into the chamber 3. A v-alve plate 5 is' attached to the-lower end of a stem B which projects through the wall of the"casting 3, and is operable to open and clos'efthe passageway and thereby to regulate the ingress .of the gas or other agent. A nut orwasher 7 is attached to the external end of the valve stem 6 and a spring 8 encircles the valve stem, abutting against! the nut or washer at one end and against an arm 9 at the other. end. The arm 9 is attached to a castin 1 has a large chamber 17 into'ioiie side of which a large pipJIS leadss A valve 6 chamber 19 is attached totheqend of the pipe 18, and has cross piecessEZOathereonu-d Another chamber .21 communicateshyvith; the

chamber 19 and has similalixoross piecesr22 therein. A valve stem 23* operates thfoughm: said cross pieces and a late Mist-attached on said valve stem, and c oses the opening into said chamber when in idle positionrandwhen 1 10 in use forms a baffle for the iii-passing 'airiafnd u 0 gas or gasolene and serves to dlstram or separate the entrained substances therefrom. Suction created within the pipe 18 by the piston in the cylinder raises the plate 24. An

iinlet passage 25 admits gasolene or gas intothe chamber 25 and is controlled by a suitable valve device 26. The passage'25 0 ens in axial a-linement with the conical end 0 the valve stem 23 so that, when idle, the said valve stem becomes seated in the passage and shuts off the passage of gasolene and gas. The chamber 21 is provided with a large air inlet 27 below the gas inlet 25 so that inrushing air takes up and carries on the gas or gasolene. A ipe 28 leads from the inlet 27 to the chain er l7 and is controlled by a valve 29, so that air may be admitted direct into said chamber before being mixed or. saturated with the gas. This does not interfere with the admission of air into the chamber 21 to carry the gas, but permits pure air to be admitted during the course of the gas saturated air to the engine.

\Vater is admitted to a receptacle 30, through a supply pipe 3] leading from any suitable source of supply, and thence through a sight feed 32 into a pipe 33. A support 34 connects said pipe with the chamber 17. The lower end of the pipe 33 opens and discharges into a valve chamber 35 whence the passage of the water is regulated by a manually operable valve 36. The valve chamber 35 opens into a chamber 37 having an outlet passage 38 for emission of surplus Water. A

. valve 39 is located in the chamber 37 and closes the passage leading from the valve chamber 35 and also the discharge outlet 38. If raised by suction or otherwise, however, said valve opens both passages and permits free passage of the water, the supply of which is regulated by the valve 36. An elbow 39 connects the chamber 37 with the pipe 18 into which the incoming gas enters and the water and gas there become saturated and entrained one with the other, and are drawn onward to the engine cylinder or point of delivery. The gas and Water are turned over and over in waves or convolutions by the angles of the passageway 3 and also within the chamber 17 where the mixed elements are permitted more or less'circulation. When desired air may be admitted into this chamber with the entrained gas and water and accompany said elements onward to their delivery.

In operation with an engine the reciprocating piston acts suctionwise upon the contents of the chamber 2. saturated gas enters said chamber it is drawn intothe cylinder-and there ignited and exploded as required to perform its functions. At or just prior to the time of the explosion the bar 10 should be moved to close the inlet passage and open the passage-1 4 for a sufiieient time for the products of explosion and When a quantity of the combustion to pass out so that the cylinder will be clear for a fresh charge. As described hereinbefore the operation of the valves may be made automatic in connection with the piston.

This mechanism is adapted for use particularly with engines wherein high power is de' vention.

Ido not restrict myself to exact details or features of arrangement orconstruction, but \Vhat I claim and desire to secure by Letters Patent, is: I

1 An apparatus of the character described comprising a chamber, an air and gas inlet passage opening into said chamber, means There may be It may as iliustrated vithin equivalentlimits, without departing from the spirit and scope of my infor, admitting water into said passage to saturate the gas, a chamber in which the water and gas are mixed and means for admitting air into the said last-named chamber, substantially as specified.

2. An apparatus of the character described comprising a passageway, means for admi.t-' ting gas into said passageway, means'for admitting water into said passa eway, an enlar ed chamber located on said passageway,

an a valvecontrolled delivery chamber beyond. the said enlarged chamber, substantially as specified.

3. An apparatus of the character described comprising a pipe, means for admitting gas into said pipe, a baflie plate in said pipe, means for admitting water into said pipe, an enlarged chamber located on said passageway, and a valve controlled delivery chamber beyond the said enlarged chamber, substantially as specified.

An apparatus of the character described,comprising a passageway, means for admitting gas and water into said passage way, an enlar ed chamber located' on said passageway a delivery chamber having inlet and outlet passages, a valve controlling each of said passages, and a single controlling de'-- vice for operating all of'saidvalves, substantial'ly as specified. I

In testimony whereof, I hereunto aflix my signature to this specification this 12th day of January 1907, in the presence of two witnesses. 7
